US leverage over Egypt
According to some analysts $1.3 billion of 'aid' buys US little or no leverage in Egypt. More important than $1.3 billion and the toys bought with it, must be a desire to stay off the US shit list. Once on that, life becomes uncomfortable as governments of current and former evil axis nations will testify. Patriotism and love of 'the people' only goes so far. The Egyptian military enjoys privileges and comforts that would be put in jeopardy by travel bans, personal financial sanctions, trade sanctions/embargoes etc.. Saudi promises to take up the slack if the west financially penalizes Egypt may become a heavy burden when you look beyond the consequences of 'aid' withdrawal and account for the impact of becoming an 'international pariah state'.
Whatever leverage the US has, it amounts to nothing if you have no desire to use it.
America Has No Leverage in Egypt
However great its hegemony may have once been in the Middle East, America no longer enjoys a strategic monopsony. Today, there are other buyers of Egyptian cooperation who can outbid the United States. Kuwait, the United Arab Emirates and Saudi Arabia together have pledged $12 billion to Egypt’s junta, and they have done so without the conditions that Congress places on American-appropriated funds.Link
